The best school lunch box for most NZ primary and intermediate kids is a leakproof stainless steel bento box of 700ml–1,500ml with compartments. It keeps wet and dry food apart, survives being dropped in the playground, and fits a standard school bag. Every lunchbox here is 304 (18/8) food-grade stainless steel, BPA-free, dishwasher safe and covered by a 3-year warranty.

School lunch box questions
Which lunch boxes fit standard school bags?
Flat, rectangular bento boxes fit best. Our Leakproof Bento 1500ml measures 21 × 14 × 5.5cm, so it slides into most primary school bags alongside a drink bottle and a reading folder. Round and oval boxes suit bags with a wider base.
Which lunch containers are most reliable for packing school meals?
Stainless steel boxes with a silicone seal and clip latches. Steel doesn't crack when dropped, and the seal stops yoghurt, dips and fruit juice leaking into the bag. Replacement seals are available, so the box keeps working for years.
Are stainless steel lunch boxes safe for kids?
Yes. 304 food-grade stainless steel is the same material used in commercial kitchens. It contains no BPA or plasticisers and doesn't absorb food smells or stains.
Can kids open these lunch boxes themselves?
Most children from age 5 can open clip latches with a little practice. Try opening and closing the box together at home before the first school day.
Do stainless steel lunch boxes keep food cold?
Our lunchboxes aren't insulated. To keep food cool until lunch, pack the box in an insulated lunch bag with an ice pack, such as the MontiiCo insulated lunch bags.
